Chiropractic is the science which is concerned with the relationship between STRUCTURE, primarily the spine, and FUNCTION, primarily the nervous system, of the human body, as that relationship may affect the restoration and preservation of health.Chiropractic is the third largest health care discipline in Canada, after medicine and dentistry; however, of these three disciplines, chiropractic is the only one based upon natural healing methods. Chiropractic physicians do not prescribe drugs or perform surgery. Instead, they respect the inherent power of the human body to heal itself. The Doctor of Chiropractic endeavors to facilitate the body’s restoration and preservation of health by helping to maintain a balanced, optimally functioning “neuromusculoskeletal system”, NATURALLY.Every aspect of the body is controlled by the nervous system. The spine has both a direct and an indirect relationship to the nervous system, and as such can influence body functions far removed from the spine itself. Because muscles and bones are intimately linked, muscles being attached to bones, the interrelationship between the nervous, muscular and skeletal systems plays a critical role in the optimal health of every organ and tissue in the body. The interrelationship between these three systems, then, is known as the “neuromusculoskeletal system”, or N.M.S. The Doctor of Chiropractic can have an effect on the N.M.S. system by making small “adjustments” to the spine, or other articulations of the body, to improve joint, muscle and nerve function.
